Transformation of qualitative variables

[ES_StatR]

Hi everyone,
I need help with a simple operation.
I have the following tibble:

tibble(months = as.character(c("April", "May", "October", "November", "December", "August", "May", "January", "February", "March", "July", "June")))

I would like to add a variable to this tibble called "season" that contains the following observation:
-"Winter" when months is = to January, February or March
-"Spring" when month is = to April, March, June
-"Summer" when month is = to July, August, September
-"Fall" when month is = to October, November, December

Thanks for the help

Hello,

Something like this?

library(tidyverse)

df_tibble <- tibble(months = as.character(c("April", "May", "October", "November", "December", "August", "May", "January", "February", "March", "July", "June")))


df_tibble <- df_tibble %>% mutate(season = ifelse(months == "January" | months == "February" | months == "March", "Winter",
                                     ifelse(months == "April" | months == "May" | months == "June", "Spring",
                                            ifelse(months == "July" | months == "August" | months == "September", "Summer",   
                                            "Fall"))))

df_tibble
#> # A tibble: 12 x 2
#>    months   season
#>    <chr>    <chr> 
#>  1 April    Spring
#>  2 May      Spring
#>  3 October  Fall  
#>  4 November Fall  
#>  5 December Fall  
#>  6 August   Summer
#>  7 May      Spring
#>  8 January  Winter
#>  9 February Winter
#> 10 March    Winter
#> 11 July     Summer
#> 12 June     Spring
